Description

Rear-mounted intelligent switch

Technical Field

The application relates to the technical field of switch correlation, in particular to a rear-mounted intelligent switch.

Background

The words switch are to be interpreted as open and closed. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches, i.e. control switches, are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closing" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" opening of the switch means that the electrical contact is not conductive, creating an open circuit, not allowing current to flow.

For the existing control switch, a groove is often required to be formed in the wall surface for installing the switch, a button is arranged on the surface of the control switch, and people can control the state of the switch through the button.

However, with the progress of science and technology and the development of society, people do not satisfy the mode of requiring people to press and control the existing control switch. Therefore, the intelligent switch is invented, replaces the existing control switch, and is internally provided with a controller which receives a wireless signal and controls whether an electronic contact in the switch is conducted or not based on the wireless signal.

However, most households are already provided with control switches, and the control switches are inconvenient to replace with intelligent switches.

The application provides a rear-mounted intelligent switch. The aftermarket intelligent switch may be mounted on the control switch. The controller is arranged in the rear-mounted intelligent switch and can receive an external control signal through the communication module to achieve control operation similar to that of the existing intelligent switch. When the controller receives an external control signal, the driver is controlled to rotate to drive the swing rod to extend out of the through hole or retract from the through hole. Therefore, the intelligent switch can receive an external control signal after being installed, and the operation of pressing the button of the control switch is simulated based on the external control signal, so that the purpose of intelligently controlling each electric appliance in a house is achieved. Therefore, on the basis of not changing the original control switch in a house, the effect of using the intelligent switch is achieved by installing the intelligent switch after the intelligent switch is installed. Specifically, the afterloading intelligent switch also comprises a power module. The power module can ensure that the afterloading intelligent switch can work normally on the premise of not damaging the control switch.

Specifically, the power module 7 is a battery. Further, the battery may be a rechargeable battery. A charging interface is arranged on the shell 1; the charging interface is connected with the rechargeable battery to charge the rechargeable battery. The charging interface is connected with the rechargeable battery through the charging circuit for charging.

So set up, when power module can't normally during operation, can't normally be when adorning intelligent switch power supply promptly, can connect the interface that charges and predetermine the power through outside electric wire, charge for rechargeable battery through the interface that charges, after rechargeable battery is full of the electricity, can be again for adorning intelligent switch power supply after, make adorn intelligent switch normal work after.

The battery may of course also be a non-rechargeable battery. When the battery is not charged, the power supply of the rear-mounted intelligent switch can be ensured only by replacing the battery.

Further, the communication module 6 includes: at least one of a Bluetooth module, a WiFi module, a radio frequency module, an infrared remote control module and a 2.4G remote control module.

In the scheme provided by the application, the communication module mainly aims to meet the requirement that a user sends a control signal to a rear-mounted intelligent switch. The communication module may be any one of the existing mature communication modules. Such as bluetooth module, WiFi module, radio frequency module, infrared remote control module mentioned in this application.

It should be noted that a plurality of buttons may be provided on the control switch. Correspondingly, the number of driving structures inside the afterloading intelligent switch provided by the application can be multiple. The rotating body and the swing rod driven by the driving structure correspond to a button on the control switch. The controller can drive a certain drive structure in a plurality of drive structures based on control signal control, drives the rotor and rotates, and then presses a certain button on the control switch.

Specifically, specific circuit connection relationships of the respective portions may refer to fig. 2.

The further driver can be a planetary motor 3 or a steering engine structure.

The planetary motor is a servo speed reducing motor. The planetary motor can carry out the pivoted turn to and the number of turns according to control command, and then can control the direction of rotation and the rotation size of rotor.

The steering engine is a position (angle) servo driver and is suitable for control systems which need to change and maintain the angle continuously. The remote control toy is widely applied to high-grade remote control toys, such as airplane models and submarine models, and remote control robots. The marine steering engine is multipurpose electrohydraulic, that is, the hydraulic equipment is remotely controlled by electric equipment. There are two types: the other one is a reciprocating plunger type steering engine which is based on the principle that work is done through conversion of high-pressure oil and low-pressure oil to generate linear motion, and the linear motion is converted into rotary motion through a tiller. The other is a rotary vane type steering engine, the principle is that high-pressure and low-pressure oil directly acts on a rotor, the size is small, the efficiency is high, and the cost is high. The steering engine is mainly composed of a shell, a circuit board, a driving motor, a speed reducer and a position detection element. The working principle is that the receiver sends a signal to the steering engine, the IC on the circuit board drives the coreless motor to start rotating, the force of the steering engine is transmitted to the swing arm through the reduction gear, and meanwhile, the position detector sends back the signal to judge whether the positioning is achieved. The position detector is a variable resistor, and the resistance value changes along with the rotation of the steering engine, so that the rotation angle can be known by detecting the resistance value. In a general servo motor, a thin copper wire is wound around a three-pole rotor, and when a current flows through a coil, a magnetic field is generated to generate a repulsive interaction with a magnet on the periphery of the rotor, thereby generating a rotational acting force. According to the principles of physics, the moment of inertia of an object is proportional to the mass, so the force required to rotate an object with a larger mass is also larger. The steering engine has high rotation speed and low power consumption, so that a thin copper wire is wound into an extremely thin hollow cylinder to form an extremely light electrodeless hollow rotor, and a magnet is arranged in the cylinder, namely the hollow cup motor. Namely: the steering engine also can control the rotator to rotate by a preset angle according to the instruction of the controller.

Furthermore, the afterloading intelligent switch provided by the application also comprises a switch;

the switch is connected with the controller 2;

sending a control signal to the controller 2 when the switch is pressed; the controller 2 receives the control signal and controls the planetary motor 3 to rotate based on the control signal.

In practical applications, the button of the control switch may be a button of a single-point pressing type, or may be a button of an upper-lower two-point pressing type. In order to enable the afterloading intelligent switch provided by the application to control the two-point pressing type button. The number of the swing rods 4 can be two; the swing rods 4 are respectively arranged on two sides of the rotating body 5. The number of through holes is also two. When the rear-mounted intelligent switch is installed on the control switch, the positions of the two through holes corresponding to the control switch are upper and lower pressing points of a button on the control switch. Specifically, the planetary motor can drive the rotor to rotate clockwise, and when the rotor rotates to the first state, the swing rod on one side extends out of the through hole. One pressing point of the button of the control switch is pressed. The planetary motor drives the rotating body to rotate clockwise and anticlockwise, and the swing rod is retracted from the through hole when the rotating body rotates to the second state. When the rotor rotates to the first state again, the swing rod on the other side extends out of the through hole (it needs to be explained that the two white rods correspond to the two through holes one by one, and the two through holes correspond to the upper pressing point and the lower pressing point of the button one by one) to press the other pressing point of the button of the control switch. In this way, it is possible to control which of the two pressing points of the push button on the switch is pressed, by adjusting the clockwise rotation and the counterclockwise rotation of the planetary motor.

It should be noted that the swing rods are respectively arranged on two sides of the rotating body. Specifically, the swing rods can be directly fixed on two sides of the rotor, and the swing rods can also be in contact with the rotor through a mechanical structure and move under the driving of the rotor to extend out of the through holes or retract into the shell.

Further, in practical applications, a plurality of buttons may be disposed on the same control switch. In order to allow afterloading of the smart switch to control multiple buttons on the same control switch. The after-loading intelligent switch provided by the application is further improved as follows:

specifically, in the post-mounted intelligent switch, one planetary motor 3, one rotating body connected with the planetary motor 3 and a swing rod 4 arranged on the outer side wall of the rotating body form a group of mechanical pressing groups;

So set up, each mechanical department of pressing corresponds to a button. For example: when the control switch is provided with three mechanical buttons with upper and lower contacts, three mechanical pressing positions can be arranged in the corresponding rear-mounted intelligent switch and are respectively used for pressing the mechanical buttons on the control switch.

Referring to fig. 4 and 5, the housing 1 includes a bottom case 11 and an upper case 12 snap-fitted to the bottom case 11. Specifically, the upper case 12 is fastened to the bottom case 11 by a snap.

So set up, drain pan and epitheca not only can closely be fixed, still convenient to detach to look over the operational aspect of the inside each device of back dress intelligence switch so that maintain it.

Further, a motor base 13 for fixing the planetary motor 3 is disposed on the bottom case 11.

So set up, the planetary motor can be fixed in motor base, and when the planetary motor clicked the operation, planetary motor self also can have the trend of removal under the effect of reaction force, and in the scheme that this application provided, can avoid the planetary motor to remove through the fixed planetary motor of motor base.

Further, the afterloading intelligent switch further comprises: and a motor fixing shell 14 buckled on the motor base 13 and used for fixing the planetary motor 3.

In practical application, a simple motor base may not be capable of completely fixing the planetary motor. In the scheme provided by the embodiment, the motor fixing shell and the motor base can jointly form an annular structure. Namely: the planetary motor is located in the motor base, and the motor fixing shell is buckled on the motor base and extrudes and fixes the planetary motor to the bottom shell.

Further, the controller 2 is a PCBA circuit board integrated with a control circuit.

It should be noted that the control circuit may refer to a control circuit inside an existing intelligent switch. The main functions realized by the control circuit are as follows: receiving the control signal controls rotation of the planetary motor based on the control signal. The circuit for receiving the control signal at present can be a bluetooth circuit, a WiFi circuit, a 5G or 4G signal circuit, etc.

Specifically, the shell 1 is made of plastic.

The housing 1 is bonded to the control switch.

It should be noted that. The after-loading intelligent switch that this embodiment provided can fix on control switch through the mode of bonding, also can fix on the switch through the mode of formula of magnetism. However, in practical applications, if the magnetic-type fixing method is adopted to fix the switch, the magnetic-type fixing method is not very firm, so that problems such as dislocation may occur, and once the after-loading intelligent switch is dislocated, the through hole of the after-loading intelligent switch may not correspond to a correct pressing point, and the after-loading intelligent switch may not be correctly pressed, so that the control switch cannot be correctly pressed. The solution provided by the present application suggests the use of a housing glued to the control switch. Specifically, the bottom shell may be provided with a protrusion thereon. Each protrusion is bonded to the control switch. When the swing rod does not extend out of the bottom shell through the first through hole, the intelligent switch is installed afterwards, and a button on the control switch cannot be pressed. When the swing rod extends out of the bottom shell through the first through hole, the swing rod can correctly press a button on the control switch, punish and press the button.
